Title: Reflection preventing film material
Inventor: ITANI TOSHIRO
IPC: G03F7/11
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent contraction or trailing of a resist pattern on a reflection preventing film which is peculiar to a chemically amplifying resist, by adding one of or both of an acid compd. and a basic compd. to the antireflection film. SOLUTION: An acid compd. or a basic compd., or both of these are added to a reflection preventing film material consisting of a crosslinking agent and a solvent, and the addition is controlled according to the acidity of a chemically amplifying resist to be used on the reflection preventing film, namely, according to the acidity of the acid produced from a photoacid producing agent. Thereby, the contraction and trailing of a resist pattern can be prevented. This is because the acidity is controlled to be almost same on the interface between the resist film 303 and the antireflection film 302 so that the deblocking reaction of the positive resist does not proceed on the interface between the resist film 303 and the reflection preventing film 302.  Moreover, no excess changes in the compsn. is required to the resist material, the gradient of solubility characteristics which largely influence the resist resolution can be maintained large, and higher resolution can be obtd.

Title: Magnetic head
Inventor: HASEGAWA SHUJI
IPC: G11B5/33
Filed: 1989-05-22
Abstract: PURPOSE:To obtain an output signal of a specified intensity by detecting the quantity of the magnetic flux penetrating a space enclosed by two branch paths. CONSTITUTION:The magnetic head is constituted of an incident path 11, branch point 12 of electron waves, the two branch paths 13, 14, a confluent point 15, and an exit path 16. A current I 111 is fed therein from an external power source 17. The leak magnetic flux 22 from a magnetic recording medium 21 is penetrated into the space enclosed with the two branch paths 13, 14 at this time. The current I flowing from the incident path 11 to the exit path 16 is, therefore, changed according to the quantity of the magnetic flux phi by an Aharonov-Bohm effect. Since the magnetic flux phi depends also on the area of the part enclosed by the two branch paths 13, 14, the reading out of recorded information is possible if this area is controlled. The output signal of the specified intensity is obtd. without depending on the traveling speed of the magnetic recording medium in this way.
